Failed Debit order midst a pandemic where everyone is cash strapped!

I feel that this is my only place where someone would assist me so hoping this helps. I want to speak to someone higher up at Home Connect. I have been debited and charged failed debit orders the last 5 months! I have changed my banking details in April and got a confirmation email with my new banking details that was send 22 April. The accounts department just makes it off as it isn't a problem but my debit orders is R750 and I don't feel it's fair to be paying for the company's MISTAKE MONTH AFTER MONTH and being promised next month the system will pick up my new details. I have spoken to them every month since May and it still isn't getting resolved and I am paying every month via EFT with immediate payment which is R50 to avoid being suspended as per their SMSs as my banking details isn't changed and according to Innocent, I didn't select my bank name on the app!The only excuse is sorry for the inconvenience and today (3 August) was told it was my fault as I didn't select my bank and I rep**** with my confirmation email and no reply from there. I am so unhappy and is so close to cancel my contract with Home Connect and switch providers.
